Patent EP-0383327-A1 (EP)
Inventor: RABE HERMANN
IPC: F22B37/56
Filed: 1990-02-15
Abstract: A steam generator for supplying steam to cooking equipment comprises a water-filled boiler comprising an automatic, level-regulated water emission, a steam discharge for automatic introduction of hot steam into a cooking chamber for the cooking equipment as needed, a heating unit operating at intervals and a decalcification arrangement having a water drain arranged close to the floor and to a side wall of the boiler for, as needed, at least partial emptying of the boiler for the purpose of flushing-out lime particles that flake off and collect on the floor of the boiler. Preferably, the decalcification arrangement comprises an arrangement for generating a flow in the steam generator that automatically kicks in at preferably adjustable intervals dependent on the operating duration and/or temperature of the heating unit to supply water to an elimination device. The arrangement for generating a flow can encompass the eliminating device and can be either a suction tube having a drain provided at the floor of the boiler; a flushing pump having a flushing admission lying diametrically opposite close to the boiler wall; or a steam pump that comprises a cooling device for the precipitation of the line particles.

Abstract: A broadband space tree-switch matrix establishes a desired switching path by sensitizing only the sequence of logic gates defined by the desired path such that only these sensitized logic gates are operable to undergo switching and thereby permit transmission of only the corresponding input signal. The tree-switch includes a plurality of cascaded stages wherein the first stage consists of dual-input NAND gates (10) each receiving a corresponding input signal (A) at one input (12) and a control signal (14) at another input (11). The remaining stages include a plurality of switching nodes (N20) each having a first NAND gate (20) cascaded to a second NAND gate (25) wherein the second NAND gate has a HIGH steady-state logic signal present at one of its inputs (24). An appropriate combination of control signals are applied to the NAND gates (10) in the first stage to effect a selected switching path. The tree-switch matrix provides low power dissipation due to the path sensitizing and exhibits minimum pulse shrinkage. A second broadband space switch matrix comprises a plurality of NAND gates arranged into a series of cascaded stages to form a tree-switch configuration. The first and second stages include equal numbers of NAND gates corresponding to the number of input signals. Furthermore, the NAND gates in only the first and second stages each have a control input for receiving control signals to establish a selected path. The tree-switch likewise operates to sensitize a particular path in response to the control signals so that only the NAND gates in the selected path are operable to undergo switching.
